On the first link on your link I find:
Some of the physicists working in this area are discovering no conflict at all between physics and belief in the paranormal and the afterlife. They are showing that the phenomena we now call “paranormal” are normal and consistent with the laws of science at the subatomic level.
So where do these 'physicists' publish their findings? Not in any reputable journals of physics that I'm aware of.
We now know that atoms are 99.999999999% empty space.
We know no such thing. The statement is meaningless.
And, thanks to 'quantum physics', we now know that subatomic particles- electrons, protons and neutrons - are not solid either. They are made up of energy. So the world we think of as being solid is in fact empty space.
There is no space without energy in it. Space with energy in it is not empty.
This means that there is plenty of room for other worlds, other dimensions, to take up the same space our own world but at a different frequency.
What 'other worlds'? What 'other dimensions'? What scientific theory is implied in the reference to 'at a different frequency'? This sounds like the nonsense that was fashionable in the 1920s and 1930s and produced a lot of bad science fiction.
Our senses and our instruments are only able to perceive a small range of vibrations between two fixed points, namely between 34,000 and 64,000 waves to the inch, or from 400 to 750 billion waves to the second. That is the section which makes up to us the physical world.
750 bn is 7.5 e+11. Our instruments can and do detect frequencies up to at least e+15 cycles / sec (photons in the γ-ray range), and I dare say a lot more.
But the physical world is only a very limited section of vibrations compared with all the other vibrations in the universe.
That's a falsifiable statement. What evidence (of scientific standard) supports it?
Scientists working in the Spirit world (which they call the Etheric world) tell us that their world is just as solid as our world but on a different frequency- just above what our senses can perceive.
I'm trying to think how to be polite about that last sentence. Perhaps I'll just ask whether when they say 'scientist' they intend to denote a trained investigator who proceeds by scientific method. And if not, why do they use the word 'scientist'?
